javah multiple classpath

I think I'm doing the 开发者_Python百科classpath wrong on the command line, and I get the following error: My android program uses Bitmap from the package android.graphics.Bitmap

thomas@THOMASDESKLINUX:~$ javah -verbose -classpath :/home/thomas/Documents/LinuxProgramming/AndroidSDKs/android-sdk-linux_x86/platforms/android-8.jar;/home/thomas/Documents/LinuxProgramming/EclipseWorkspace/RenderScene/bin org.me.renderscene.Billboard
Error: No classes were specified on the command line.  Try -help.
bash: /home/thomas/Documents/LinuxProgramming/EclipseWorkspace/RenderScene/bin: is a directory

and javah cant find the class

thanks!

The problem with your command is that you are using the Windows Path Separator ; on the command line, rather than the Linux Path Separator :. I also recommend to add the current directory to javah: ., the correct command to generate header in your case is:

javah .:/home/thomas/Documents/LinuxProgramming/AndroidSDKs/android-sdk-linux_x86/platforms/android-8.jar:/home/thomas/Documents/LinuxProgramming/EclipseWorkspace/RenderScene/bin org.me.renderscene.Billboard

Tip: javah doesn't need all dependency libraries to generate the headers, it will output warnings but thats OK. So using this tip, we can generate the headers with:

javah .:/home/thomas/Documents/LinuxProgramming/EclipseWorkspace/RenderScene/bin org.me.renderscene.Billboard
